Authorization bypass through User-Controlled key vulnerability in Apache Camel K.

An authorization vulnerability in custom resource resolution allows a tenant to reference secrets by name in the operator namespace, potentially exposing secrets belonging to other tenants or operator components.

This issue affects Apache Camel K: from 2.0.0 before 2.9.3, from 2.10.1 before 2.10.2.

Users are recommended to upgrade to version 2.9.3, 2.10.2 or 2.11.0, which fixes the issue.

It was found that the Apache Camel XSLT component would resolve entities in XML messages when transforming them using an xslt: route. A remote attacker able to submit messages to an xslt: Camel route could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.

It was found that the Apache Camel XSLT component allowed XSL stylesheets to perform calls to external Java methods. A remote attacker able to submit messages to an xslt: Camel route could use this flaw to perform arbitrary remote code execution in the context of the Camel server process.
